PAPER-BAG MACHINE.

ESPECIPICATION forming part of Letters Patent No. 37 L361, dated December 6, 1887.

Application filed March 7, 1887. Ser'al No. 229,914. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. HoNIss, of Hartford, Connecticut, have invented an Improvement in Paper Bag Machines, of

which the following description and claims constitute the specification, and which is illustrated by the accompanying sheet of drawings.

This invention is an apparatus for retractio ing apaper-bag blank along the surface on which it is lying in a. machine wherein it is being made into a paper bag in order to cause other devices appurtenant to that bed to perform other operations upon that blank.

1 This apparatus, together with its proper environment in a paper-bag machine, is shown in Figs. 42 and 43 of the drawings of Letters Patent of the United States, No. 361,951, granted to Lorenz and Honiss, April 26, 1887,

on a paper-bag machine, and the same matter is briefly described in accompanying specification, but is not claimed therein.

Figure 1 of the present drawings is a side view of my present invention and its proper environment; and Fig. 2 is a like view, but

with the parts in another position.

The numeral 1 indicates an arm pivoted to the hub'2 of the cylinder l80,and having the sector 3 attached thereto. The sector 4 is pivoted on the stud 5, and is rocked by its arm 6, which carries a roller, 7, running in the earn-groove 8, and which groove is cut in an adjacent stationary disk. The arm 9 is pivoted to the shaft 224, and is attached to a 5 rigid projection from that shaft by the spiral spring 10, so as normally to be held in contact with the shoulder 11. The arms 1 and 9 are provided with working-surfaces at their ad jacent ends, which surfaces are both arcs of 0 circles and nearly or quite in contact with each other. -A duplication of the arm 1 and integral therewith is preferably made on the diametrically-opposite side of the shaft of the cylinder 180; but in that case the indicated 5 eccentricity in the groove 8 must also be likewise duplicated. The other parts of the drawings are identical with the corresponding parts shown and illustrated in the said Letters Patent of Lorenz and Honiss.

The mode of operation is as follows: Whenever during the revolution of the cylinder 180 the roller 7 reaches the eccentricity in the camgroove 8, it rocks the sector 4,and thus retards the forward movement of the arm 1. That retardation retards the forward movement of the arm 9 against the resistance of the spring 10, and thus retracts the bag-blank 12, which is grasped between the working-surfaces of the two arms. After that retracting has been accomplished,the two arms 1 and 9 revolve forward out of conjunction and the arm '1 is returned to its previous position relative to the cylinder by means of the roller 7 running out of the eccentric part of the camgroove 8,while the arm 9 is returned to its previous position relative to the shaft 224 by means of the contractile action of the spring 10. The same general result may be obtained by stopping the motion ofthe arm 1 as by retarding that motion.

I claim as my invention 1. The combination of the arms 1 and 9, pivoted substantially as described, and operatingtogether, substantially as set forth,to retract the bag-blank along the surface of the blank-carrying cylinder or carriage, all substantially as described.

2. The combination of the cylinder 180, the arm 1, pivoted to the axis of that cylinder and provided with the sector 3, the sector 4, piv- 8o oted on the stud 5 and rocked by the arm 6, and the. cam 8, all constructed and arranged so that the arm 1 may revolve with the cylinder 180, and will periodically be retarded or temporarily stopped in that rev0lution,substantially as described.

Dated March 4, 1887.

WILLIAM H. HONISS.
